STRUCT MARVELL_NFC_CAPS(9)

✨ NAME ✨

okay so this is struct marvell_nfc_caps — it's literally the NAND controller capabilities struct, and its whole ~thing~ is telling different compatible strings apart from each other 💅 this is struct marvell_nfc_caps(9) from the Kernel API Manual, bestie, and it's lowkey iconic.

🌸 SYNOPSIS 🌸

struct marvell_nfc_caps {
    unsigned int max_cs_nb;
    unsigned int max_rb_nb;
    bool need_system_controller;
    bool legacy_of_bindings;
    bool is_nfcv2;
    bool use_dma;
    unsigned int max_mode_number;
 };

yes bestie there's a stray space before that closing }; in the original — we do not touch, we do not fix, we respect the source 🫶

🎀 Members 🎀

okay buckle up, one field at a time, no cap:

• max_cs_nb — how many Chip Select lines you get. that's the number, that's the whole vibe 💅
• max_rb_nb — how many Ready/Busy lines are available. count 'em.
• need_system_controller — a bool that says whether the SoC needs to have access to the system controller (like, in order to enable the NAND controller). so it's giving "i can't do it alone, i need my support system" energy 😭
• legacy_of_bindings — a bool that says whether DT parsing must be done the old fashioned way. yes, the old fashion way, that's the original wording, we're keeping it fr fr 🙈
• is_nfcv2 — a bool — NFCv2 has numerous enhancements compared to NFCv1, i.e. the BCH error detection and correction algorithm, and the NDCB3 register has been added. glow-up behavior honestly ✨
• use_dma — a bool — use dma for data transfers. fast girlie behavior 🔥
• max_mode_number — the maximum timing mode that the controller supports. it's giving limits, but make it fashion 👑
